IMPROVEMENT IN LAMPS.

fitlgt steamer it in flgrse itttters than in making out at its sane.

TO ALL 'WHOM'IT MAY oononan:

Be it known that we, JOHN Bnnso'n, EPIIRAIM DANIELS, and JbANNA FARRELL,of 257 West Thirty-First street, in the'city, county,'and State of NewYork, have invented a new and useful Improvement in Lamp- Burners; andwe do hereby declare the following to be a full, clear, and exactdescription thereof, which will enable those skilled in the art to makeand use the same, reference being had to the accompanyingdrawing,forrning part of this specificationflnwhich drawingi i i Figure 1 is avertical cross-section of our improvement.

Figure 2 is a horizontal section. I

This invention relates to means for operating the wicks of lamps, andeonsists,in general terms, in making the parts which raise and lower'the wick in such a manner thatthey will not injure the wick, and alsoin such a manner that they can be easily adjusted so as to take hold ofthe wick with more or less pressure, as may be desired. I

In carrying out our invention, we employ rollers, whose peripheries maybe roughened or serrated, or left smooth, as may be preferred,'.and saidrollers are so arranged that they are on opposite sidesof the wick-tube,through openings wherein their peripheries project, so as to take holdof the wick.

The letter Adesignates the usual metalliecase which closes the top of alamp, and which usually sustains the wiek-tube,-and encloses thewick-feeding apparatus. The letter B designates the wick-tube, whosesides, opposite the feeding-apparatus, are cutaway, as at J J, to allowthe peripheries of the feeding-rollers D D to approach the wick C, whichis contained in said tube. .The feeding-roller D is mounted in bearingsin the'sides of a fixed frame or box, F, that extends across the case,past both edges of the wick and wick-tube, and its shaft projectsthrough and beyond the case A far enough to receive, on one end,.awheel, E, by means of which it is turned. The feed-roller D is mountedin a movable box, G, which is arranged and fitted to slide-within thefixed frame F, as is shown most clearly in fig. 2, being moved to andfro therein towards the feed-roller D, or in a reverse direction,bymeahs of a screw, I, whose inner end is connected to the sliding box Gin such a manner as to turn thereon, and whose screw-thread works in ascrew-thread tapped in the boss K, formed in the wall of the case orshell A. The ends of the axis of feed-roller D extend through and beyondthe'ends of the sliding box G, into horizontal slots H H, formed intheends of the fixed frame F, which slots,.a.ocordingly, in

conjunction \vith the axis of roller D, form guides for the movements ofthe. sliding b'ox G and its feed-roller, and also support them in theframe F. Instead of supporting and guiding the feed-roller D and its boxin the frame'R the sides of case A can be used for that purpose, and theroller 'D-can be also supported in bearings formed in case A. a i

The rollers D D are, in this example, made with smooth peripheries, butthey can be more or less roughened,

or one can be smooth and the-other rough. We also modify them byreducing their diameter in their middle or central parts, so that theywill only take hold of the wick at their ends, and at those parts'wherethey are left of their full diameter. I

In operating and using our invention, we adjust the roller D, by meansof its screw I, to such a position, with respect to the opposite rollerD, as to compress the wiekC, interposed between, sufil ciently to feedit or move it upwards or downwards, as may be necessary. I Our inventionenables us to operate a trick with ease and exactness, and withouttearingth'e wick, as is often done by the serrated feeding-disks nowcommonly used.

What we claiin as new, and desire to secure by Letters Patent, is

In combination with the ordinary stationary roller D, the roller D",mounted on a sliding box, G, operated by the swirel-serew K,substantially as and for the purpose described.
